A novel strategy for green synthesis of colloidal porphyrins/silver nanocomposites by Sesbania sesban plant and their catalytic application in the clean oxidation of alcohols

摘要

Highlights?Self-organized nanoporphyrins synthesized in the presence of silver nanoparticles using Sesbania sesban plant.?Templates, harmful organic solvent, and assisted self-assembly of porphyrins were completely missed in this strategy.?Different alcohols were oxidized in high yields and excellent selectivities in water as a green solvent.?Catalyst and oxidant’s byproduct can recycle and reuse.AbstractSelf-organized organic nanoporphyrins were synthesized in the presence of bio silver nanoparticles (AgNPs) using extracted Sesbania sesban plant (ESS). For this novel nanohybrid, [(Ag/MnP)NPs], with the size of 15?nm, manganese (III) meso-tetraphenylporphyrin complex (MnP) was used along with host-guest solvent methods. This nanobiomaterial was characterized by scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), a
